TO ALL .WHOM IT MAY CONOERN:

Be it known that I, B. F. BEAM, of Ada, in the county of Hardin, and intheState of Ohio, have` invented a new and improved CombinedShovel-Plough and Cultivator; and I (lo-hereby declare that thefollowing `is ak full, clear, and exact description thereof, Ireferencebeing had to the annexed drawings, making part of this specification, inwhieh 1 l Figures' 1, 2, and 3 are plans or top views, showingrespectively my improved implement arranged for a. double, triple, andsingle-'shovel plough.

Figure 4 is a side elevation of iig. 1 or 2; and.

Figure 5 shows a part in detail, to be more particularly referred tohereafter. l

The nature of my invention consists in so constructing the parts of acultivator that it may be used with oner two, or three shovels, and thechange of condition effected with facility, without making any materialalteration in. its general structure, whilefat the same time it'will beso balanced that it will not overset when left to rest on two' shovels,as seen in iig. 1--a -quality which will greatly enhance the ease withwhich it may be worked. v

In the drawings, A is the draught-beam, to which are attached thehandlesB B, a. shovel or plough, C, and al coulter, D, when this may bedeemediexpedient. The front end of the draught-beam may be furnishedwith a clevis, if desirable, for adjusting the draught. When it isrequired Vto use two shovels, as in iig. 1, a sliding adjustablegauge-beam, E, is? used. An elevationof this is shown Vin g. 5.. Thisgauge-beam has a cleft or mortise .in itsuper edge, iu which is receivedthe draught-beam A, to a depth nearly equal to its vertical \vidth. Theupper edge of the beam is somewhat cambercdor arched, so that it ishighest at its middle. A metal bar,- F, bent down at its ends, as shownin fig.v5,is bolted along on the top of the beam E, in such a mannerthat it may be tightly held on the draught-beam A, and prevented fromsliding along on it after being fixed at any point in its length. Aspace, equal to the thickness of the draught-beam QA, is left betweenthe ends of the gauge-beam E and the turned-down ends of the bar F.Another shovel, C', is now bolted by the front end of its draught-beam,a, to the front end of the draught-beam A, while the draught-beam apasses through and is held from lateral motion in the space 'between theend of the beam E and bar F. A guide-bar, G, is bolted to the other sideof the front end ofthe draught-beam A, and its rear end, whichis bentfor the purpose, is engaged by the beam E and bar F, on the oppositeside from the shovel C. The front ends of the beam a of the shovel C areheldby two bolts b which pass through them and the beam. The Coulter D,when used,

may also be secured bywone or both bolts b.. When three shovels arewanted, it is only necessary to substitute aniither shovel and beam, Ca, for the guide-bar G. v

The shovels may be setat any "required and proper distance from eachother by changing the position of the gauge-beam E on the beam A,securing it in its place by drawing down the bar F by its bolts, andloosening one and tightening the other of the bolts` b b.

I claim as new, and desire to secure by Letters Patent- 'Ihe gauge-beamE, constructed substantially as described, in combination with the beamsA and a, guidehar G, shovels or ploughs C C', or any of them, andco'ulter D, substantially as and for the purposes set forth.

In testimony that I claim the above-described improved combined ploughand eultivato'r, I have hereunto signed my name, this Q-Sddayof JulyA.D. 1867.

B. F. BEAM.
